Abstract
A small size, flat panel, 1/6.sup.th wavelength antenna is provided. A flat copper-clad dielectric substrate is processed on a first flat side to produce a copper triangular or pseudo triangular-shaped radiating element having a linear copper feed line that extends from the triangle apex. The substrate is also processed on its opposite flat side to produce a rectangular-shaped first copper ground plane element that underlies at least a portion of the copper feed line, but does not underlie the copper radiating element. The first side of the substrate may also be processed to produce a second copper ground plane element that is out of physical engagement with both the copper feed line and the copper radiation element. Aligned through holes are formed in the first ground plane element and the substrate. The metal sheath of a coaxial cable connects to the copper ground plane member(s), and the cable center conductor penetrates the aligned through holes and connects to the copper feed line. The antenna substrate may be a portion of a printed circuit board, or the like, that is within a mobile wireless communication device, such as a laptop computer or a cellular telephone. The antenna …
